SPECIFICATION forming part of Letters Patent No. 542,470, dated .my 9, 1895. Application filed September 13, 1894. Serial No. 522,906. (No model.)

.To @ZZ whom, it 'may coz/merio.-

Beit known that I, EDWARD WEREIBURG- HOUSE, ofHiawatha, in the county of Brown and State of Kansas, have invented certain new and useful Improvements in Harrows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable .others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in harrows.

The object of the invention is to provide an improved disk harrow or cultivator exceedingly simple, durable, and economical in construction and composed of a minimum number of parts to accomplish the functions desired, and which can be easily and quickly adjusted to the various positions desired.

The invention consists in certain novel features of construction Vand in combinations of parts more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings, Figure l is a rear elevation of the improved disk harrow. Fig. 2 is a top plan thereof. Fig. 3 is a longitudinal section through one gang of disks. Fig. 4 is a vertical cross-section. Fig. 5 is a detail section through the toothed disks holding a gang of disks.

In the drawings, o c, are two parallel transverse beams constituting the frame of the harrow and rigidly held a suitable distance apart by the sleeves b on the bolts c, passing transversely through the beams. Each beam is preferably formed of an angle-iron with the vertical edge or side at the inner side of the beam. A

d is the tongue preferably extending across and secured to both beams and having the brace-rods extendingtherefrom and secured to the frame by said bolts o.

e is the drivers seat secured on therear portion of the tongue. v

f are the barrow-disks of any suitable or ordinary construction.

The disks are here shown arranged in gangs,

three disks to each gang. Howevenl do not wish to limit myself to such specific arranges ment. The' disks of each gang are mounted on a suitable horizontal shaft g. Each gang of disks is provided with an upwardly-extend- 5 5 ing frame h, preferably inverted-V shaped, having the disk-shaft mounted in its lower ends. The lower ends of each frame h are flanged (see h) to t the separable boxings h, secured together and to said flanges by 6o the bolts h3.

The squared shaft g passes through the two sleeves g', which rotate with the shaft and in the boxes h.' The center disk is clamped between the inner heads of the two sleeves g. One end disk is clamped between the outer head of one sleeve and a head on the shaft g, while the outer end disk is clamped between the outer head of the other sleeve and a washer gf. This end of the shaft g is 7o threaded and all the disks and sleeves are clamped thereto and in position by the nut gi.l This is a most durable and effective mode of securing the disks to the shafts and condning them to the hangers.

The upper end of the frame above the disks is provided with the vertical toothed disk j, having the central depression around a horizontal bolt-hole. Each frame h is attached to a rotatable hanger k, having a shank at its 8o upper end journaled in and passing up through a slot l, arranged snugly between the beams of the frame with ianges m extend- Y ing under said beams. The horizont-al portions of'the beams are provided with elon- 85 gated slots n, for each block, which determine the range of lateral adjustment of the gangs of disks. The Iianges m of each block have clamping-bolts o passing up through said slots so as to clamp the block and the 9o gang in the desired lateral adjustment. The lower end of each hanger has the vertical toothed disk 'p meshing with the teeth of the frame-disk, and with a central circular boss q fitting in the said central depression of the 9 5 frame-disk.

r is a horizontal clamping bolt passed through said two toothed disks of each gang, whereby they are clamped together to hold the gang in the desired vertical adjustment. roo Each clamping-bolt r is extended forwardly a nsuitable distance. A stirrup s surrounds prising the toothed disks and bolts.

the outer front portion of said bolt, and braces t t are secured thereto and extended downwardly and secured to the lower ends -of thel frame h. -The upper end of each rotatable hanger has a cross-head u, secured rigidly thereon so as to rest on the block Z and eX- tend forwardly and rearwardly beyond the beams of the frame. These braces t t are preferably secured to the braces by being clamped to the ends of rearwardly-extending rods t t', having their front ends passed through and secured in eyes h4 in the lower portions of frams h. rPhe rear ends of the two rods t t of each gang ofdisks adjnstably carry the horizontal bars t, which have the cleaners t3 secuted thereto. The cleaners can be moved toward and from the disks by moving the bars t longitudinally through the rear ends of the arms t.

The front end of each cross-head is secured to the outer end of the horizontal clampingbolt of its particular gang by the vertical rod or bolt c. A most strong and rigid construction is thus formed to cause the gang to turn with its cross-head and to brace and strengthen the gang against rearward strain when the harrow is in operation.

o! a are two metal brackets secured to the rear end of the tongue and extending laterally in opposite directions. Each bracket is provided with a rack.

h b are the two levers for adjusting the gangs horizontally. Each lever is mounted on one of said brackets to swing in a plane parallel with the length of the frame, and is provided with a hand-clip and pawl to hold the lever in any position desired in connection with the bracket-rack. The two levers are thus arranged on opposite sides of the rear end of the tongue at therear side of the machine. The rear end of each cross-head has an eye-bolt c loosely mounted therein. The connections d, loosely secured to the 1evers, extendthrough the eye-bolts c of their respective gangs, and are adj ustably clamped therein by set-screws. The outer end gangs are connected with the levers on their respective sides of the machine, while the inner gangs are connected respectively with the levers on the opposite sides of the machine. Thus it will be observed that the gangs on the same side of the machine are rocked horizontally in opposite directions, which is very desirable when cultivating crops in rows where it is desired to throw the soil to or from the plants. j

It will be observed that the gangs can be adj usted laterally toward or from each other by reason of the slidable blocks and the slots in the frame; also, that each gang can be rocked vertically and held in the desired p0- sition by reason of the sectional frames com- When the bolt is loosened the disks can be turned on eachother and 'then clamped in the desired position, whereby the dirt von either or both sides of ridges can be worked as in listed corn; also, by means of the levers and adjustable connections to the gangs, the gangs can be turned to any desired angle to the line of draft.

It is evident that various changes might be made in the forms, constructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence, I do not wish to limit myself to the `particular construction herein set forth.

Having thus fully described my invention,

what I claimgas new, and desire to secure by Letters Patent of the United States, is-
